Benefits of technology

[0005]A defensive shield for a ship has a support arm pivotally mounted to a ship, and a shield pivotally mounted to an end of the support arm. In one embodiment, the shield is outwardly spaced from the ship, and may be selectively positioned between first and second deployed positions. In the first deployed position, the shield is raised abo

Problems solved by technology

The added mass of the armor plating, however, may reduce the ship's speed and maneuverability.
Additionally, fixed or integrated armor plating does not allow for a spatial separation between the armor plating and the ship's hull, thereby prohibiting the selective re-positioning of the armor independently from the position of the ship.
Thus, while the armor may protect the ship, protection is limited to only those places wherein the armor affixes to the hull.
This does not protect the ship in all places and leaves the ship venerable to certain types of attack, such as aerial and underwater attacks.

Embodiment Construction

[0013]Referring now to FIG. 1, one embodiment of the present invention is shown therein and indicated generally by the number 10. Defensive shield 10 comprises a support arm 12, and a shield 14. A hinge 16 pivotally mounts the support arm 12 to a ship 60, while another hinge 16 pivotally mounts the shield 14 to an end of the support arm 12. As will be described later in more detail, ship 60 may include a control system to independently position support arm 12 and shield 14, thereby allowing the defensive shield 10 to assume a plurality of defensive postures to defend against aerial and underwater attacks, for example.

[0014]The support arm 12 may be an articulating arm. For example, FIG. 2 illustrates the support arm 12 as a telescoping arm comprising an extendable shaft 12a, and a sleeve 12b that receives an end of extendable shaft 12a. An extension controller 30 controls the movement of the shaft 12a, such that shaft 12a extends out of, and retracts into, sleeve 12b. Those skilled ...

Abstract

A defensive shield for a ship has a support arm, pivotally mounted to a ship, and a shield pivotally mounted to one end of the support arm. The support arm is movable between a retracted position and a plurality of deployed defensive positions. In the deployed positions, the shield is outwardly spaced from the ship and angled to defend against attacks, such as aerial attacks and underwater attacks.

Description

[0001]This application is a continuation-in-part of now abandoned U.S. application Ser. No. 09 / 981,602 filed Oct. 18, 2001.BACKGROUND OF THE INVENTION[0002]The present invention relates generally to defensive systems and, in particular, to defensive shields used by ships to defend against attacks.[0003]Military vessels are usually equipped with defensive armor plating to protect against attack. The armor plating frequently comprises a thick, heavy plate that may be affixed to, or is integral with, a ship's hull. The added mass of the armor plating, however, may reduce the ship's speed and maneuverability. Additionally, fixed or integrated armor plating does not allow for a spatial separation between the armor plating and the ship's hull, thereby prohibiting the selective re-positioning of the armor independently from the position of the ship.[0004]Thus, while the armor may protect the ship, protection is limited to only those places wherein the armor affixes to the hull. This does n...
